To all whom it may concern:

Be it known that I, Louis BRUCKER; a. citizen of the United States, residing at Bostonfin the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Sweepers; and I do hereby declare the following to be a full, clear, and exact'description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sweepers.

The object of the invention resides in the provision of a device for sweeping dust, dirt, litter, etc., from the surface of floors, carpets and the like, which will besimple in construction and comparatively inexpensive to manufacture.

The invention comprises a casing for receiving dirt swept from a floor or the like through the instrumentality of a traction operated rotary brush associated with the casing, and a pivoted cover for said casing adapted in its movementqto open position to force dirt .previously deposited in the; forward end of the casing to the rear thereof.

In describing the invention in detail ref erence will be had to the accompanying drawings wherein like characters of reference denote corresponding parts in the .s eral views, and in which,

Figure 1 is a plan view of the sweeper constructedin accordance with the invention; Fig. 2, a side elevation. thereof; ,Fig. a section on the line3-3 of Fig. 1;Fig. 4'. a section on the line 4.4 of Fig. 1, with the cover of the casing shown in open position: Fig. 5, a detail view of the detachable brush employed in the sweeper; and, Figs. 6 and 7, fragmental sectional views of the traction wheels and. their associated parts which support and rotate the brush shown in F 1 Referring to the drawings, the invention is shown as comprising a casing 10 having its front end and rear portion of its top. open. Secured to the respective sides of the casing 10 and projecting laterally therefrom are brackets 11 and 12 in which are journaled respectively shafts 13 and 14:. Fixed on the outer end of the shaft 13 is a wheel 15 preferably of iron with a tire of hard rubber, while a similar wheel 16 is fixed on the outer end of the shaft 14. The inner end of the shaft 13 is extended in the Patented an.

form of a hollow member provided at its inner end with a notch 18. Likewise, the shaft 14 is provided at its inner end with an extension in the form of a hollow member 19, the inner end of which has an '0' n portion as at 20. Mounted in the hollow member 19 is a spring 21 adapted to be compressed by the insertion of one end of the. spindle 22 of a rotary brush 23, through the opening 20. Said spindle has the end adapted for insertion in the opening 20 enlarged as at 2 1 so as to efliciently engage one end of the spring '21. The other end of the spindle 22 is enlarged as at 25 and so shaped as to be capable of movement transversely of the hollowmember 17 through the notch 18 of said member.

From the construction just described it will be apparent that in order to mount the brush 23 between the hollow members 17 and 19 it is only necessary to insert the enlarged end 24 of the spindle into the opening 20 of the inember 19'and compress the spring 21. This compression of the spring 21 will move the brush23 longitudinally.

and bring its enlarged end 25 within the longitudinal limits of the notch 18 when said end 25 can be moved transversely of the member 17 through the notch. hen the end 25 has been so moved the brush 23 is released to the influence of the spring 21 and as a result moved toward the member 1'? carrying the outer extremity of the end 25 beyond the outer longitudinal limitation of the notch 18 and when so disposed the brush is securely locked between the members 17 and 19 for rotation therewith. The brush 23 may be as easily detached from the members 17 and 19 by reversing'the operation just described. I I

Secured to respective sides of the casing 10, just rearward of the closed portion of the top of said casing are upstanding ears 26 and 27 provided with vertical slots 28 and 2) respectively, while a cover 30 adapted to close theopen portion of the top ofthe casing is provided intermediate its ends at opposite sides with arms 31 and 32 projecting through the slots 98 and 29 'respec tively, thus providing a shifting pivotal connection between the cover and the cztsing. The outer ends of the arms 31 and 32 are enlarged as at 33 and 34: respectively to prevent disengagement of the arms from the upstanding ears through which they extend. The forward end of the cover 30 has attached thereto a flexiblestrip o preferably. of rubberadaptedto engage the bottom of the casinwhen said cover is moved to open position in order to sweep the dust disposed at theforward end of the casing to the rear thereof. During this opening movement of the cover it will be apparent that its forward end will move into engage ment with the bottom of the casing and that" the upward movement of the arms 31 and 32 in the slots 28 and 29 respectively will permit eontinuedmovement of. the forward end. of the cover along the bottom of the easing. A socket 38 secured to and projecting rearwardly from the rear endof the, casin 1O is'adapted to receive a handle 39'- inor er that the device may be conveniently manipulated.

What is claimed is:

1 A sweeper comprising in combination a casing having its front and the rear portion of its top open, a tract-ion operated rotary brush disposed across the open front of said casing, a pair of upsta'nding ears provided with -vertical slots secured to o'p- I posite sidesof said casingat the inner-end, Y of the closed portion of the top thereof a,

cover for'closing the open portion of the-top of the casing, an arm projecting vlaterally from each side of the cover intermediate the ends thereof and passing through the slots in adjacent upstanding ears; and a flexible strip secured across the forward end of said cover adapted to engage the bottom of the casing as said cover is moved to open position.

2. A sweeper comprising in combination a casing open. at its front, a bracket secured toleach side of the casing and projecting' laterally thereof. a shaft ournaled 1n eac of said brackets, a wheel fixed on the outer end of each of said shafts, a hollow member extending from the inner end of one of said shafts provided at its inner end with a notch, a second hollow member extending from the inner end of the other shaft prowided with anopening in its inner end, a

spring disposed within said last named hola casing hating its front andthe rear portionof its top open, a traction operated rotary brush disposed across the open front of said'casing, a pair of upstanding ears provided with vertical slots secured to opposite sides of said casing at the inner end of the closed portion of the top thereof, a cover for closing the open portion of the: top of the .casing and an arm projecting laterally from each side of the cover intermediate the ends thereof and passlng through the slots 1n ad acent upstandlng ears.

In testimony whereof, I afiix my signature, in presence of two witnesses.

I LOUIS BRUCKER.
